CLUSTER CLOUD-READER-READING · 43 ENTRIES · EARLIEST ENTRY 2012-05-31
Ebook readers and converters
This cluster comprises 26 products centered on ebook reading and format conversion, offering features like annotation, cloud sync, and multi-format support. Their dated entries appear sporadically from October 2010 to July 2026, usually one per month with occasional months having two, showing no clear trend in growth. Among traction leaders, Lorebound has the highest activity signal with 2 stars, while Thorium Reader and Syncer have 0 stars each.
Entry timeline
ENTRY TIMELINE
Each bar is the month a member carries, which is a creation date where the source published one and a crawl date otherwise. Nothing in the index was found before 11 August 2026, and coverage broadened sharply on 14–15 August, so a bar from then on reports how much we found that month, not how much was built; an earlier bar reports how far back a member's own source dated it — not how long we have been watching.
